oh yea my bad

If a magnet passes through the copper tube at a uniform rate would eddy currents still be formed because when a magnet falls through a copper tube normally, it accelerates so i was wondering does there have to be an acceleration or not? :) edit: follow up question: if u put slits the the copper...
